Onycholysis is a common medical condition characterized by the painless detachment of the nail from the nail bed, usually starting at the tip and/or sides. [1] On the hands, it occurs particularly on the ring finger but can occur on any of the fingernails. It may also happen to toenails. Onycholysis can occur in many conditions, including ...
In chemistry, a hydridonitride (nitridohydride, nitride hydride, or hydride nitride) is a chemical compound that contains both hydride (H −) and nitride (N 3−) ions.These inorganic compounds are distinct from inorganic amides and imides as the hydrogen does not share a bond with nitrogen, and usually contain a larger proportion of metals.
Onycholysis is a loosening of the exposed portion of the nail from the nail bed, usually beginning at the free edge and continuing to the lunula. It is frequently associated with an internal disorder, trauma, infection, nail fungi, allergy to nail enhancement products, or side effects of drugs.
Together with its conjugate base superoxide, hydroperoxyl is an important reactive oxygen species.Unlike • O − 2, which has reducing properties, HO • 2 can act as an oxidant in a number of biologically important reactions, such as the abstraction of hydrogen atoms from tocopherol and polyunstaturated fatty acids in the lipid bilayer.
Pseudomonas aeruginosa is a common bacterial cause of green nail syndrome. Green nail syndrome is caused when the nail is exposed to a bacterial organism, which leads to opportunistic infection. [9] Pseudomonas aeruginosa, the most common cause but not the only one, [10] is frequently found in nature including in water sources, humans, animals ...
Causes [ edit ] Growing older or having poor biomechanics , which are more common in the elderly (e.g., toes that overlap and underlap; incompatibility between the foot and the shoe; or digiti flexi, which is characterized by contracted toes due to toe buckling caused by shortening of the controlling muscles), may be contributing factors.
Distal subungual onychomycosis is the most common form of tinea unguium [2] and is usually caused by Trichophyton rubrum, which invades the nail bed and the underside of the nail plate. White superficial onychomycosis (WSO) is caused by fungal invasion of the superficial layers of the nail plate to form "white islands" on the plate. It accounts ...
Usually hydrolysis is a chemical process in which a molecule of water is added to a substance. Sometimes this addition causes both the substance and water molecule to split into two parts. In such reactions, one fragment of the target molecule (or parent molecule) gains a hydrogen ion. It breaks a chemical bond in the compound.
